when the value of the parameter is increased the point was moved to 54.75 mils
away from the anchor point along the x axis and 65.25 mils along the y axis; the
original distances multiplied by the scaling factor of 1.5.
Radial Dimension Parameters
A radial parameter defines a dimension using an anchor point, a reference point
and an adjustable point set. The nominal value of the parameter is defined by the
distance between the anchor point and the reference point. When the dimension is
varied, each point moves along a line extending from the anchor point through it’s
original position. Setting up a radial parameter is identical to setting up an anchored
parameter. When defining your radial parameter, you perform the following
steps:
• You select the anchor first. This is the fixed starting point for the
parameter.
• You select the reference point. The reference is the first point in the
adjustable point set, which is the set of points moved relative to the
anchor point when the value of the radial parameter is changed. The
diagonal distance from the anchor point to the reference point is the
value of the dimension parameter. When the value of the dimension
parameter is changed, the anchor retains the same position, but the
reference point, along with the adjustable point set, moves to a new
position.
• Third, you select any additional points in your circuit you wish to move
when the reference point moves; this is the adjustable point set. As the
value of the dimension parameter is varied, the reference point, as well
as the rest of the adjustable point set, is moved accordingly. Each of the
